Top 6 Reasons Why Drag and Drop Fails on Mac External Drives

Before attempting fixes, it helps to identify why your Mac is blocking file transfers to your external storage media.

How to Fix Drag and Drop Issues on Mac (7 Proven Methods)

Work through these step-by-step methods to resolve drag-and-drop file transfer issues on your Mac.

Fix 1: Enable Full Read-Write Access for NTFS Drives

If your external drive is formatted in NTFS (which you can check by right-clicking the drive icon and selecting 'Get Info'), the simplest and safest solution is using Donemax NTFS for Mac.

Donemax NTFS for Mac is a lightweight, reliable utility that grants full read and write access to Windows NTFS drives on macOS. It eliminates the read-only boundary instantly without requiring you to reformat the drive or erase your existing files.

Step 1:  Download and install Donemax NTFS for Mac on your MacBook or Mac desktop.

Step 2:  Connect your NTFS external drive to your Mac.

Step 3:  Launch Donemax NTFS for Mac, select your drive, and click 'Enable Writable' button. The software will then make the NTFS drive fully writable on Mac.

Step 4:  Open Finder and freely drag and drop any files or folders directly onto your NTFS drive!

Fix 2: Modify Folder Permission Settings in Finder

If the drive format is APFS or Mac OS Extended, permissions might be preventing file transfers:

1. Right-click your external drive icon on the desktop or sidebar, and select 'Get Info'.
2. Expand the 'Sharing & Permissions' section at the bottom.
3. Click the lock icon and enter your Mac admin password to make changes.
4. Change your privilege setting to 'Read & Write'. You can also check the box for 'Ignore ownership on this volume'.

Fix 3: Restart Finder or Relaunch macOS

If drag and drop stops working completely across your system, restarting Finder often resolves temporary glitches:

1. Press Option + Command + Esc to open the Force Quit menu.
2. Select 'Finder' from the list and click 'Relaunch'.
3. Alternatively, restart your Mac from the Apple Menu > Restart.

Fix 4: Run First Aid in Disk Utility to Repair Drive Errors

If macOS locked the drive because of file system irregularities, repair it using built-in diagnostic tools:

1. Open Finder > Applications > Utilities > Disk Utility.
2. Select your external drive from the left sidebar.
3. Click the 'First Aid' button at the top toolbar and select 'Run'.
4. Wait for Disk Utility to scan and fix directory errors, then try dragging files again.

Fix 5: Free Up Storage Space on the External Drive

Check if your external drive has sufficient capacity. Open 'Get Info' on the drive and review the 'Available' space. Delete unneeded files or clear the Mac Trash while the drive is connected.

Fix 6: Check Cables and Try Another USB Port

Disconnect your external hard drive and inspect the cable connector. Plug the drive directly into a motherboard USB-C or Thunderbolt port on your Mac, bypassing USB extension cables or unpowered hubs.

Fix 7: Reformat the External Drive (Last Resort)

If the drive file system is severely corrupted and you do not need the files stored on it, reformatting will create a fresh file system:

1. Open Disk Utility, select the external drive, and click 'Erase'.
2. Choose exFAT (for Windows & Mac compatibility) or APFS (for Mac-only use).
3. Click 'Erase'. Note that this will permanently delete all contents on the drive!

Best Practices for Smooth Mac External Drive Usage

Adopting these simple daily habits will keep your external drives healthy and prevent file transfer issues:

1. Always Eject Drives Safely:  Always click 'Eject' in Finder before disconnecting your external drive to prevent partition errors.
2. Keep Donemax NTFS Installed:  Use Donemax NTFS for Mac to maintain seamless cross-platform reading and writing without reformatting.
3. Do Not Interrupt Copy Operations:  Avoid unplugging cables during active file transfers to prevent corrupting file allocation tables.
